You are probably remembering a drive on the Cascade Lakes Highway (Scenic Byway aka Century Drive) where you can drive from one lake to another. You can get to the road via Sunriver (heading west towards Mt. Bachelor). Some of the lakes that you may recall the names of: Todd, Sparks, Elk, Devils, Hosmer, Cultus, and Crane Prairie Reservoir. The major river in the area is the Deschutes
Here's a description of each lake and its amenities:
